موضوع به انگلیسی:The effect of novel coronavirus pandemic
on tourism share prices
بخشی از متن:Abstract
Purpose – This paper aims to provide swift feedback to readers and investors on the early effect of novel
coronavirus (COVID-19) pandemic outbreak on tourism industry.
Design/methodology/approach – Three leading consolidators of hotel accommodations, airline tickets
and travel services in the tourism industry around the globe, namely, Booking Holdings Inc., Expedia
Group and Trip.com Group Ltd. are chosen in this study. First, numerical description is performed on
their shares prices and a set of control variables to compare their performances before and during the
lockdown because of COVID-19 outbreak. Next, this paper estimates ordinary least squares models with
and without exponential generalized autoregressive conditional heteroskedastic specification to
establish the nature, significance and magnitude of the pandemic’s early effect on the shares
performance of these online travel companies (OTCs).
Findings – This paper discovers a rapid decline in the performance of tourism industry amid the
pandemic outbreak, from the perspective of three leading OTCs, which derive their profits from tourists
by providing them online hotel reservation, air-ticketing and packaged-tour business services around the
globe. These significant adverse direct and indirect effects testify that tourism-related businesses are
extensively locked down by the pandemic outbreak.
Research limitations/implications – Future studies are encouraged to examine each of the tourism
sectors for individual effects.
Practical implications – This paper provides implications for investors to protect their wealth, and for
policymakers to ensure sustainability of tourism industry in the pandemic outbreak and in the future.
Originality/value – From the perspective of corporate finance, this paper empirically quantifies the early
effect of COVID-19 on tourism industry for a quick snapshot.

موضوع به انگلیسی:Sensitivity and vulnerability of international tourism by covid crisis: South
America in context
بخشی از متن:The aim of this research is to visualize those countries that would have the greatest impact in terms of sensitivity
and vulnerability due to the drop in travels, as a product of the pandemic, with special emphasis on South
America. For this, the participation of tourism in the economy of certain countries prior to the coronavirus crisis
was measured by analysing three groups of countries: the ten most tourist countries in the world according
to their receipts; countries whose economies are most dependent on tourism; and the twelve South American
countries, contextualized through the other two groups. Thus, multiple combinations of high, low and medium
sensitivity and vulnerability were identified for South American and for the countries with the highest absolute
receipts from tourism, but an alarming scenario for the most dependent countries on international tourism,
many of them small island countries in development (SIDS). Additionally, the ideas of low apparent sensitivity
and that of low sensitivity due to role inversion offer new ways to interpret a low sensitivity. Likewise, and with
respect to vulnerability, three possible stages of recovery of international tourism activity were noted

موضوع به انگلیسی:Triazole, imidazole, and thiazole-based compounds as potential agents
against coronavirus
بخشی از متن:The expansion of the novel coronavirus known as SARS‐CoV‐2 (severe acute respiratory syndrome coronavirus
2), COVID‐19 (coronavirus disease 2019), or 2019‐nCoV (2019 novel coronavirus) is a global concern over its
pandemic potential. The need for therapeutic alternatives to stop this new pandemic is urgent. Nowadays, no
efficacious therapy is available, and vaccines and drugs are underdeveloped to cure or prevent SARS‐CoV‐2
infections in many countries. Some vaccines candidates have been approved; however, a number of people
are still skeptical of this coronavirus vaccines. Probably because of issues related to the quantity of the vaccine
and a possible long‐term side effects which are still being studied. The previous pandemics of infections caused
by coronavirus, such as SARS‐CoV in 2003, the Middle East respiratory syndrome coronavirus (MERS‐CoV) in
2012, HCoV‐229E, and HCoV‐OC43 were described in the 1960 s, ‐HCoV‐NL63 isolated in 2004, and HCoVHKU1identified
in 2005 prompted researchers to characterize many compounds against these viruses. Most
of them could be potentially active against the currently emerging novel coronavirus. Five membered nitrogen
heterocycles with a triazole, imidazole, and thiazole moiety are often found in many bioactive molecules such
as coronavirus inhibitors. This present work summarizes to review the biological and structural studies of these
compound types as coronavirus inhibitors

موضوع به انگلیسی:Understanding environmental terrorism in times of climate change:
Implications for asylum seekers in Germany
بخشی از متن:With an increasing global population and undeniable climate change, environmental terrorism is causing unprecedented
levels of human insecurity. The use of resources as weapons of armed conflict is particularly effective on vulnerable
societies, triggering large-chain global migration-related issues. This research advances the understanding of
environmental terrorism, addresses the connections of resources and conflict, and the effects of climatic events on
these phenomena. The existing related body of literature was scrutinized and complemented with an in-depth empirical
study of 100 asylum seekers from 17 countries hosted in German facilities. The results point to the use of environmental
terrorism by governments or opposition groups, or both, in Syria, Iraq and Afghanistan. Interviewees provided
accounts of how perpetrators oppressed and harmed their enemies and civilians by attacking, drastically reducing or
cutting the supply of resources, such as water or electricity, and by contaminating water with disease-causing agents.
This paper elaborates on the conflict in Syria by presenting empirical evidence on the climate's contribution to the
armed conflict in order to demonstrate that environmental terrorism is particularly effective on populations living
in drought-stressed regions. Considering that 81% of interviewees reported observing water or electricity scarcity –
or both – in their place of origin, this research claims that mounting climate pressure on resources is likely to increase
the use of environmental terrorism, thereby contributing to migration and human insecurity across regions. The purpose
of this research is to inform academia and policy makers on the strategic importance of monitoring and
preventing resource related threats and violence.

موضوع به انگلیسی:Real-life adherence to subcutaneous
immunotherapy
بخشی از متن:Background: Allergen immunotherapy (AIT) must be continued for 3 years, to achieve a longterm
modifying effect. Adherence is a key to ensure effectiveness. The objective of this study
was, first of all, to evaluate the adherence with subcutaneous immunotherapy (SCIT) and to identify
the main causes of SCIT withdrawal in real-life practice in our clinic. Secondly, we also aimed to
investigate to what extent the COVID-19 pandemic altered our SCIT receiving patients’ treatment
adherence behaviors and the factors that affected their decisions.
Methods: Retrospective analysis of the medical records of patients ages 18 years, who had
started SCIT in January 2014 or later until September 2020 in our department for the diagnosis of
allergic rhinitis, allergic asthma or venom allergy, were included in the study. Adherence was
determined as the accomplishment of 3 years of SCIT
